SportsLog: Redskins backup quarterback Kirk Cousins is open to a trade

League sources told ESPN that Redskins backup quarterback Kirk Cousins is open to being traded. Cousins wants to start but Robert Griffin III is blocking his path in Washington. Cousins was drafted in the fourth round of the 2012 draft by Washington, and has performed well as backup to Griffin. Cousins has appeared in eight games (four starts) and passed for 1,320 yards with eight TDs and 10 interceptions . . . Sunday marked another milestone in the demolition of the Metrodome in Minneapolis. The cables that supported the facility’s famous roof were severed as construction crews set off about a dozen explosive charges. The Metrodome is being torn down to make way for a new $1 billion Vikings stadium.
